摘要
将图像线性特征机助提取的Ｈｏｕｇｈ变换方法与五步卷积方法结合，并将这种改进的图像Ｈｏｕｇｈ变换方法引入到了重磁数据的处理与解释中．研究了用Ｈｏｕｇｈ变换方法机助提取重磁资料中的构造信息的可行性、基本原理以及计算流程．最后，给出了一个用图像Ｈｏｕｇｈ变换方法机助提取淮南煤田颖凤地区重力资料构造特征的实例．
Hough transformation is integrated with method of the five step convolution of image linear information. The Hough transformation of improved image is introduced to processing and interpretation of gravity and magnetic data. The feasibility, basic principle, and calculation procedure for extraction of gravity and magnetic data by Hough transformation are investigated. Finally, an example is given of computer aided information extraction from gravity data in Yingfeng area of Huainan coal field.
